Just a tip that has seemed to work for me so far. Take your time and be patient, tell yourself it's going to take 4 hours alone to remove the hardware properly; get a 12 pack of your favorite beverage, crank up the tunes and get to work.
- Take your torx screwdriver and slowly turn left 1/8 turn.
- Turn right 1/8 turn.
- Repeat steps 1 and 2 about 5 times (all this does is loosen the threadlocker and nets zero movement on removing the bolt).
- Then turn left 1/4 turn and right 1/8 turn.
- Repeat step 4 as many times necessary until the threadlocker has broken free enough to loosely spin out with almost no effort.
